The integrated peripheral controller contains an IDE interface with support for two IDE channels.
Select
Enabled to activate each channel separately. The settings are: Enabled and Disabled.

store data for faster perform-ances.
Primary/Secondary Master/Slave PIO
The four IDE PIO (Programmed Input/Output) fields let you set a PIO mode (0-4) for each of the
four IDE devices that the onboard IDE interface supports. Modes 0 through 4 provide successively
increased performance. In Auto mode, the system automatically determines the best mode for each
device. The settings are: Auto, Mode 0, Mode 1, Mode 2, Mode 3, Mode 4.
Primary/Secondary Master/Slave UDMA
Ultra DMA/33 implementation is possible only if your IDE hard drive supports it and the operating
environment includes a DMA driver (Windows 95 OSR2 or a third-party IDE bus master driver). If
your hard drive and your system software both support Ultra DMA/33 and Ultra DMA/66, select
Auto to enable BIOS support. The settings are: Auto, Disabled.
Init Display First
This item allows you to decide to activate whether PCI Slot or AGP Slot. The settings are: PCI
Slot, AGP Slot.
IDE HDD Block Mode
Block mode is also called block transfer, multiple commands, or multiple sector read/write. If your
IDE hard drive supports block mode (most new drives do), select Enabled for automatic detection
of the optimal number of block read/writes per sector the drive can support. The settings are:
Enabled, Disabled.
Onboard FDD Controller
Select Enabled if your system has a floppy disk controller (FDD) installed on the system board and
you wish to use it. If you install add-on FDC or the system has no floppy drive, select Disabled in
this field. The settings are: Enabled and Disabled.
